齿轮新旧标准精度结构和精度指标关系分析

The Analysis of Structure and Tolerance Limitation of the New and Former National Standard On the Gears Accuracy

从齿轮新标准精度标注出发,提出了同级指标间的功能等价概念,概括了新旧标准精度结构要点和旧标准精度结构的前提,分析和比较了新旧标准精度结构;通过齿轮精度指标关系分析,揭示了旧标准精度结构的缺陷和新标准精度结构的相对合理性。希望有利于新标准体系的学习和应用,以及相关课程的教学。

The structure and tolerance limitation are analized and compared for the new and former national standard on gear accurany. The conception of “equivalent function” is presented. The shortcoming of old standard and the advantage of new standard are presented.
